IMPROVEMENT IN WATCH-CHAINS.

Specification forming part of Letters Patent N 0. 182,853, dated October 3, 1876; application filed August 24, 1876.

To all whom it may concern Be it known that I, J OHN J. ROHRBACH, of the city and county of San Francisco, California, haveinvented an Improved Watch-Chain and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had tothe accompanying drawings.

My invention relates to certain improvements in the construction of link watch-chains and it consists in anovel formation of the links, which are united, so that when either of the two opposite sides are presented to view it will give the appearance of a heavy bar-link gold chain, but, when turned so that the other sides are exhibited, the appearance of a quartz or other ornamental setting will be given. My invention also relates to a novel construction ofthe link and an ornamental band, so that the link may have an opening at the side for the convenient introduction of the small joining-links.

Referring to the accompanying drawings, Figure 1 is an edge view of my chain. Fig. 2 is a side view. Fig. 3 is a view showing a divided link.

A A are long bar-links, of which my chain is composed. These links are formed with an opening, B, as shown in Fig. 1, and the opposite faces are struck up or stamped with depression to hold the ornamental blocks of glass, crystal, agate, quartz, or whatever may be used. These are put in, preferably, in two When finished one side of the link is sawed.

apart, as shown at D, Fig. 3, and the small links E, which unite thelarger or mainlinks A,

are inserted through the opening thus made.

In order to close and conceal this opening, and at the same time finish and ornament the chain, I form a clasp or band, F, which slips over the link, so as to cover the opening D, and is suitably secured in place.

The small connecting-links Emay have an ornamental link, G, between them, or otherwise so united as to retain the links A all in the same position, so that a view in one direction will produce the efiect of a gold bar-link chain, while a view from the other side will show the ornamental stones or setting.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As a new article of manufacture, a chain consisting of the open bar-links, A having the sides fitted to receive an ornamental setting, and so united by the links E G as to present either the metal-edge view or the ornameutale face view, substantially as herein described.

In Witness whereof I have hereunto set my hand.
